Dear Listmembers, Although the position not directly is related to stable isotopes, I decided to post it on the list anyway. Please, forward it to the right people in your department. WANTED: POST-DOCTORAL FELLOW IN COMBINED METAMORPHIC PETROLOGY AND GEOCHRONOLOGY Supervised by David R.M. Pattison (U Calgary) and Larry Heaman (U Alberta) THE PROJECT: We are seeking a highly motivated post-doctoral fellow to examine the petrogenesis and isotopic systematics (mainly U-Pb) of accessory phases in the Ballachulish aureole, Scotland. The extensively studied Ballachulish aureole provides an ideal natural setting to examine the petrogenesis of accessory phases as a function of bulk rock composition and metamorphic grade, and to examine their comparative isotopic systematics in a single, well controlled setting. Several major lithologies/bulk compositions have been affected by the contact metamorphism (pelites, quartzites, siliceous dolomites, impure limestones, metabasites), giving rise to a wide range of accessory minerals useful for U-Pb dating, including zircon, monazite, baddeleyite, rutile, titanite, apatite, allanite and xenotime. Most of the lithologies have been studied in detail with respect to conventional metamorphic petrogenesis. Although the initial focus will be on accessory phases useful for U-Pb dating, it may be possible to expand the project to include a comparative study of Rb-Sr, Sm-Nd and Ar-Ar mineral systematics on the same samples as a function of metamorphic grade within the aureole.
